12 Claims. 1

This invention relates to cable lashing machines such as used for spinning a lashing wire about an aerial cable and its supporting strand or messenger.

Machines of this character usually include a trolley adapted to be moved along the messengerr provided for the spinning head on the trolley.`

Provision must also be made to drive the spinning head responsive to movement of the trolley along the messenger. These requirements have heretofore necessitated relatively complex driving structures involving the use of gates to permit removal of the lashing machine at the completion of a span at one side of a pole and rfa-application of the machine to the next span at the opposite side of the pole. Another dilculty is that the driving wheel may slip on the cable supporting strand by reason of wet or greasy spots thereon so that proper tension is not maintained on the lashing wire or strand.

Therefore, principal objects of the present invention are to provide a cable lashing machine of simple, light weight construction and which is readily removed and applied to a cable supporting strand in an expeditious manner, and to provide a dual drive, one through traction on the cable supporting strand and the other responsive to withdrawal of the lashing strand from the spinning head so that at least one of the drives is always effective.

Other objects of the invention are to provide a cable lashing machine with driving connections that simplify removal and application of the machine to a cable and supporting messenger; to provide the trolley and spinning head with registrable passageways or gaps through which the cable and supporting strand pass when removing and mounting the machine; to provide a locking mechanism for retaining the trolley and spinning head with the passageways or gaps in registry; to provide an improved driving mechanism that eliminates the necessity of connection and disconnection with respect to the driving head; to provide a rolling support for the driving head which acts in conjunction with ment and driving engagement of the driving head in all positions thereof;l to provide the trolley with a traction wheel driven by traction with the messenger to operate the driving connection with the spinning head; to provide readily adjustable means for maintaining desired tractional contact of the Wheel with the messenger; to provide the lashing machine with means for collecting and supporting the rings by which the cable is temporarily carried from the messenger; and to provide an improved tensioning mechanism for applying the desired amount of tension on the lashing wire as it is being laid around the cable and its supporting messenger.

In accomplishing these and other objects of theA invention I have provided improved structure, the preferred form of which is illustrated in the accompanying drawings wherein:

Referring more in detail to the drawings: I designates a cablelashing machine embodying the features o theU present invention and 1 which includes a trolley 2 and a spinning head 3. the driving connection to maintain Xed align- 55 The trolley 2 includes a" substantially tubular and I respectively (Fig. 4).

3 body 4 having a longitudinal slot or gap 5 in the underside thereof to permit mounting of the machine on a cable supporting strand as later described. The ends of the tubular body are provided with flanges 6 and I (Fig. 4) to which are bolted substantially disk-like heads 8 and 9. The heads 8 and 9 have slot-like openings or gaps I and II (Figs. 4 and 7) registering with the longitudinal 'gap 5 of the tubular body 4. The head 9 has a track I2 extending therearound to cooperate with a track member I3 (Figs. 4 and that is interposed between the flanged end 6 of the tubular body 4 and the head 8. The surfaces I4 of the track are preferably formed on an angle of substantially 45 relative to the axis of the tubular body. The heads, including the track'member I3, are bolted to the tubular body by suitable fastening devices such as bolts I5 Mounted on the rear face of the head 91s a wheel housingV I'I including an upper fixed section I8 and a lower hinge section I9. The pper section I8 has a radial flange 20 extending outwardly therefrom to secure the section to the head 9 by means of fastening devices 2l that pass through suitable openings in the flange and into threaded sockets of the head. The lower section conforms in shape to the upper section and has an ear 22 (Fig. 5) projecting from the flange 23 (Fig. rI) thereof which forms a continuation of the flange 20. The hinge section is secured to the head 9 by a fastening device such as a cap screw 24 (Fig. 5) that extends through an opening in the ear and into a threaded opening of the flange of the head. The opposite end of the flange 23 engages in a keeper 25 (Fig. 5) that is offset laterally from the adjacent face of the head 9 to support the sections in registry. The annular wall of the sections curves' inwardly as at 26 to encircle a circular opening 2'I that registers with the passageway 28 through the tubular body (Fig. 4). The hinge section carries a block 29 (Figs. 4 and '7) that is-'fixed to an inwardly extending lug 30 of the section and which engages in and 'closes the notchelike opening or gap II of the head 9 vand provides a continuation of the track I2. The hinge section I9 is adapted to be latched 'in closed position relative to the iixed section of the housing by a slide bolt 3I reciprocable in a bore 32 o'i the block 29 and e'nl.

gageable in a registering bore 33 formed in the head 9, thebolt being normally` projected by a spring 34 (Fig/8) seated in the bottom of the bore 32 and engaging the end of the bolt 3fI. The bolt is moved to retracted position against action of the spring 34 bymeans of a lateral pin 35 which projects through a slot 36 in the block 29 as shown in Fig. `4.Y Y

Extending inwardlyfrom the upper section of the housing are spaced lugs 3'I and 38 vmounting the ends of a cross pin 39 which journals a wheel 40. The wheel 40 has 'a grooved periphery 4I conforming` to the contour 0f a cable supporting strand o'r messenger and on which the wheel is y' adapted torou "for supporting that end of the trolley. Co-op'erating with 'the wheel 40 is a roller 42 that is journalled on a lcross pin 43 carried by spaced

arms

44 and 45, which arms are pivoted on a cross pin 46 (Fig. '4) carried by the lug 3D previously described. Thearms `44 and are adapted lto ybe 'moved toward the wheel 40 to engage the underside of a cable supported by the I'l'ss'e'g'ei. This hlOv'ement is 'effected by means of set screws 41 threaded angularly through openings passing through the hinged section I9 of the housing and through internal lugs 48 to engage the undersides of the

arms

44 and 45 as shown in Figs. 4 and 7. rIhe rear end of the trolley is guided laterally with respect to the messenger by laterally spaced vertically disposed

rollers

49 and 50 that are carried on arms 5I and 52 pivotally mounted within the upper housing section on cap screws 53 (Fig. 5) which are secured to the lugs 3'I and 38. The arms are retained against adjusting

screws

54 and 55 by coil springs 58 and 5l. It is thus obvious that through manipulation of the adjusting screws, the rollers are moved toward and from the axial center of the housing.

Mounted on the head 8 is a forwardly extending hood-like housing 58 having

side walls

59 and 60 located on the respective sides of the gap I and a top 6I. The hood-like housing is preferably formed of two sections secured together by fastening devices such as bolts 62 extending through abutting flanges 63 on the respective sections. The rear of the side walls have laterally extending flanges 64 through which cap screws 65 are extended for attachment of the housing (Fig. 5).

Rotatably mounted within

bearings

61 and 98 that project outwardly from the side Walls of the housing is a shaft 69 and xed thereto within the housing is a wheel 'I9 having a resilient section Il that is provided with a grooved periphery 'l2 for mounting the forward end of the trolley on the messenger. The shaft 69 is connected by a flexible coupling 'i3 with a spining head driving mechanism I4 later described. Traction is maintained between the wheel I9 and messenger by a tensioning roller 'I5 that is rotatably mounted on a shaft 'I9 having one end pivotally connected to an arm TI by a hinge joint i8. The opposite end of the shaft is adapted for support within the fork end 'I9 of an arm 80 and which is secured therein by a knurled nut 8l threadingly mounted on the end of the shaft as shown in Figs. 2 and lil. The arms TI and 89 are located on the respective sides of the wheel 'I0 and have bearing portions B2 and 83 carried on the shaft 99. The arms are connected together by a cross member 94 to which is secured an eye that is located in front of the wheel 19, Engaged with the eye is a hooked end 89 (Fig. 4) of a threaded rod 81 which extends upwardly through an opening 89 of the hook-'like housing and carries a coil spring S9 that is sleeved thereover and which is tensioned by a knurled nut 99 threaded on the projecting end ofthe rod. It vis thus obvious that by rotating the nut and compressing the spring, any desired tension may be effected on the messenger between the roller 'I5 and the wheel l for a purpose later described.,

The cable, 'later described, is guided for entrance into the tubular body of the trolley by means of a spool-like rollel` 9I rotatably mounted on a cross shaft 92 having one end hingingly connected as at 93 with a swivel head 94 on a post 95 (Fig. 3). The post 95 is located on one side of the gap i9 of the head 8 and has a reduced threaded shank 96 threaded into a socket 91 of the head. The opposite end of the shaft is received in a slotted end 98 of a post 99 similarly anchored in the head 8 at the opposite side of the opening.

VrIhe latter end of the shaft mounts a thumb nut IUD which is adapted' to be threaded against the notched end of the post to prevent displacement ofthe roller when the roller is in position to guide the cable.

The cable spinning head includes a tubular body of larger diameter than the tubular body of the trolley `and is coaxially mounted therewith by means of rollers |02 and |03 that are journalled on anges |04 and |05 located at the respective ends of the tubular body (Fig. 5), the rollers being secured to the flanges by eccentric bushings |06 mounted on cap screws |01. The faces of the rollers engage the faces of the tracks previously described. Attention is directed to the fact that there is a sufficient number of rollers located in circular series about each end of the tubular body to support the tubular body of the spinning head in coaxial relation with the tubular body of the trolley and whereby sufficient rollers are at all times engaged with the tracks to maintain coaxial alignment while other of the rollers are moving across the gap in the track member I3 at the forward end of the trolley. Since the gap at the rear end of the trolley is closed by the block 25, the rollers |03 for that end may be differentially spaced if desired. When play may occur between the faces of the rollers and the faces of the tracks, it may be taken up by adjustment ofthe eccentric bushings |06 on the cap screws |01.

Spaced inwardly from the ends of the tubular body of the spinning head are flanges 09 and I0 :which have gaps formed therein in registry with the slot-like opening of the tubular body of the spinning head. The space between the tubular body of the spinning head and the outer circumference of the flanges |09 is closed by side walls i|| and ||2 (Figs. 4 and 7). The outer peripheries of the flanges carry a cover 0r shield ||3 that is secured thereto by fastening devices ||4 to provide an enclosure for the spinning body, supporting wheels at the rear end of the trolley as well as to enclose a lock and a driven wire tension wheel later described.

The spinning head is adapted to be rotated about the axis of the tubular body of the trolley under dual drives, one of which is effected by frictional contact of the wheel 10 with the messenger when the lashing machine is in use. This is accomplished by providing the tubular body of the spinning head at a point adjacent the flange |09 with a sprocket segment ||5 having ends H6 and ||1 terminating on the respective sides of the gaps formed in the tubular bodies 4 and lill. Operating over the segmental sprocket is a chain ||6 carried by idler sprockets ||9 and |20, the idler sprockets being located so that a run |2| of the chain is at all times in engagement with a sufficient number of teeth of the sprocket to effect a drive therewith even when the gap between the ends ||6 and ||1 is passing the space between the sprockets ||9 and |20. The chain also operates over a driving sprocket |22 as shown in Fig. 2. The chain and sprockets are mounted within a housing extension |23 that is carried on an annular flange |24 encircling the head 6 but which terminates at the sides of the head so as to avoid blocking of the passageway to the gaps formed in the tubular body of the trolley.

It is obvious that upon rotation of the foremost wheel 10 of the trolley, the shaft 69 is rotated to actuate the gears |36 and |30, the shaft |3| and the sprocket chain ||8 to effect rotation of the spinning head when the lashing machine is moved in one direction.

Formed within the cover I3 at one side thereof is a recess |62 extending to the tubular body of the spinning head and of a size to accommodate a coil of lashing wire |43 on a spool |44. The spool 44 includes a disk |45 having a hub |46 journalled on a pin |41 that is fixed by a bracket |46 to the tubular body of the spinning head. The outer end of the hub |46 is reduced in diameter and exteriorly threaded to mount a plate |48 that cooperates with the plate |45 to retain the coil of wire therebetween. The hub is retained on 'the pin by a collar |49 sleeved on a projecting end of the pin and retained by a cotter pin |50 that extends through an opening in the collar and through a registering opening in the end of the coil supporting pin |41.

Also located on the spinning head at a side of the coil of wire, is an idle pulley |5| that is provided with a groove |52 through which the lashing wire is extended in guiding relation to a spinning wheel |53. The wheel |5| is mounted for idle movement on a cap screw |54 projecting from the spinning head. The spinning wheel |53 is adjustably supported from the tubular body of the spinning head by a bracket |55 having laterally spaced arms |56 slidable within bores of a block |58 that is secured to the tubular body by fastening devices such as cap screws |59 as shown in Fig. 4. Positioned on the bracket is a tubular spindle |6| that extends laterally therefrom through a notch-like opening |62 in the shield H3, the opening being of suitable size t0 accommodate the spinning wheel |53. Sleeved on the tube is a spacing washer |63 and a wheel |64 that is connected with a hub |65 of the spinning wheel. The wheel |64 is preferably formed of two parts |66 and |61, the part |61 being formed as an integral part of the hub |65 of the spinning wheel and the part |66 being clamped thereagainst by fastening devices such as screws |68. The peripheries of the wheel sections are grooved to mount a tire |69 which is adapted to frictionally engage the inner face of the head 9 so that a supplementary drive is provided for rotating the spinning head incidental to pay of the lashing wire from the spinning wheel as later described. VThe tubular spindle is retained in position on the bracket by a fastening device such as a bolt |13 having its shank |14 extending through a retaining washer |15 seated'within a counterbore of the spinning wheel and through the tubular spindle into a threaded socket of the supporting bracket.

In order to prevent retractive movement of the agresse;

trolley. and ftoY maintain tension on the lashing wire, as later described, the shaft 99 is provided at a point within the hood-like housing with a ratchet wheel |11 adapted to be engaged by a pawl |18 best shown in Fig. 9 which isv xed to theshaft 69 by a pin |19. The pawl is mounted on a pin |30 carried. by a side wall of the hoodlike housing. The pawl has a tail portion |8| to be engaged by a cam |82 on a shaft lever |83 GFig. The tail of the pawl is lretained in contact with the cam' by a coil spring |84 having one end'flxed to the tail portion of the pawl and its other end secured to a pin projecting inwardly of thehcod-like housing as best shown in Fig. 5.

To facilitate placement of the machine, it is desirable to lock the spinning mechanism relative to the trolley so that the gaps of the tubular bodies are in registry. This is effected as shown in Fig. 6 by a rod |35 slidable in an opening |86 inthe flange H9 and in a tubular socket |81 projecting laterally from the flange |09. Fixed on the rod is a collar |93 for seating a spring |89 that is coiled about the rod and has its opposite end seated against the flange ||0 to normally eiect retraction of the free end |90 from engagement with an opening 19| in the head 9. The rod is selectively move-d into engagement with the opening by a lever |92 that projects through a bayonet slot |93 in the shield I3. The

To facilitate movement of the rod, the tubular socket |8'ti has a bayonet slot |91 corresponding to the bayonet slot just described for guiding Va pin |99'carried by the rod as shown in Fig. 6.

In order to eifect movement of the machine along a cable supporting strand, the forward end thereof is provided with rings |99 and '209 located on the respective side of the opening and which are adapted to be engaged by snaps 2 0! and 202 fixed to

branches

204 and 205 of a rope 206.

Aerial cables 201 are usually temporarily supported by rings 299 from the messenger 209 and to gather up these rings progressively with the spinning, the arms 11 and 80 previously described have tubular guides 2|0 and 2|| (Fig. 7) welded thereto for receiving the Shanks 2|2and 2|'3 of fingers 2id and 2|5 to ride on the respective sides of the messenger and engage in the rings 209 to effect collection thereof as shown in Fig. 1.

ported from the strand 209 by the rings or the equivalent 298, the strand being supported on poles (not shown). The machine is applied to 'the strand adjacent the end of a span. This is effected by bringing the slot-like gap of the spin- -ning head into registry with the slot-like gaps -of the tubular body of the ytrolley and locking the parts in this position by means of the rod |85. To

releasing the latch 3|.. The cable. guiding spool or= roller 9| is swungout of position in registry with the'slot-like gap l0. This is effected by loosening `the thumb nut |00 until it clears the slotted end ofthe post |99. Then, the spool may be swung outwardly and turned on the swivel joint so. that it isout ofposition as shown in Fig. 7. The tension roller 15 is similarly loosened and moved from in front'of the traction wheel. The machine is then ready to be applied to the cable supporting strand.

To apply the machine, it is supported so that it is passed over the strand with the strand en= tering the tubular body through the slot-like gaps. The

traction wheels

10 and 40 then upport the machine upon the cable carrying strand. The hinge section |9 is then closed and latched and the tension roller 15 is moved to a position under the cable supporting strand 209 as shown in Fig. 4. After securing the tension roller by retightening the thumb nut 8|, the cable guiding spool 9| is similarly moved into position so that it is supported transversely directly below the cable 201. The pawl |18 will then be engaged with the ratchet wheel |11. The end of the spinning wire is loosened from the coil, passed into the groove of the pulley |9| and wrapped about the spinning wheel |53. The end is then anchored by a suitable clamp to the adjacent pole that carries the cable supporting strand. The rope 206 is attached to the machine by connecting the snaps 20| and 202 with the rings |99 and 200. The thumb nut 90 on the threaded rod 91 is turned to adjust tension of the roller 15 on the strand 209. The

guide rollers

49, 59 and l2 may then be adjusted by means of the

set screws

40, 41, 54 and`55. The locking device is then disengaged by shifting the arm |92 out of the elongated portion of the bayonet slot and into the lateral portion thereof to effect and retain disengagement of the locking rod from contact with the head 9 of the trolley. The spinning head is then free to revolve about the body of the trolley.

When draft power is applied to the rope 206 the machine is drawn along the cable supporting strand. Traction of the wheel 1| with thestrand causes rotation of the shaft 69, gears |39 and |38 to rotate the shaft |35, sprocket |22 and endless chain ||8. Engagement of the chain with the teeth oi the ring member ||75 eiects rotation of the spinning head about the axis of the trolley. Since the driving chain is in contact with a greater extent of teeth than the spacing between the ends I9 and l |1 of the sprocket member, rotation of the spinning head is continuous. Rotation of the spinning head carries the coil of spinning wire about the aerial cable and its supporting strand so that the lashing wire |42 is laid in a series of spirals to closely bind the aerial cable to the messenger as shown at the right of Fig. l.

Since the lashing wire |42 has been wrapped about the spinning wheel, pay of the lashing wire rotates the spinning wheel |53 and since the spinning wheel is connected with the friction wheel |69 and the friction wheel rolls on the head 9 of the trolley, a supplementary driving force is effective whereby to rotate the spinning head. Thus, as above pointed out, I have provided a primary and supplementary drive so that should the traction wheel 10 engage wet or greasy spots in the Ycable and tend to slip the driving force is maintained through the friction wheel |69 with the result that a constant and substantially uniform tension ismaintained on the lashing wire.

TheV driving ratio effected between the primary and supplementary drives is such that when the machine is used on a medium sized cable the driving forces are substantially equal in effect; however, when the machine is used on smaller or larger cables, there is some differential between the drives and it is desirable that one of the drives be adjusted. This may be readily effected by ad.- justing the thumb nut 90 to vary the spring action on the roller 16 which regulates the traction of the driving wheel 'lil so that any differential between the drives may be compensated for.

Attention is directed to the fact that the block 29 closes the gap in the head and track for the Wheel |69, when the lower section of the wheel housing is closed, thus providing a continuous track so that the driving force of the spinning wheel is continuous.

As the machine is moved progressively along the cable carrying strand, the fingers 2 I4 and 2|5 engage the temporary supporting rings and collect them thereon as shown in Fig. 1.

When the machine has reached the end of the span, the lashing strand is secured to the adjacent pole after which the slot-like gap of the spinning head is moved into registry with the slot-like gap of the tubular body of the trolley. The hinge section of the wheel housing is then opened and the tension roller 'l5 and cable guiding roller 9| are moved out of position so that the entire machine may be lifted from the messenger and re-applied on the opposite side of the pole. The machine is then re-adjusted on that side of the pole as above described and the operation is continued to complete lashing of the aerial cable to its supporting strand.

From the foregoing it is obvious that I have provided a cable lashing ma-chine of simple construction wherein the spinning head is driven Without the use of a gate in the driving connections and at the same time the spinning head is maintained in concentric registry with the tubular body of the trolley. It is also obvious that with the primary and supplementary drives at least one of them is effective at all times to maintain uniform tension on the lashing wire and therefore the spirals are of substantially uniform length.
